"Quick - name the most important personal computer of the late 1970s and early 1980s. Those of you who mentioned the legendary Apple II - that's fine. I respect your decision. Forced to think objectively in 2012, I may even agree. But if you just named Radio Shack's TRS-80, you made me smile. Your choice is entirely defensible. And back in the TRS-80's heyday, I not only would have agreed with it but would have vehemently opposed any other candidate."

You CAN blow people's minds with your new RAD skillz! Folks looking to do some Z80 programming often do their own programs for the old Sega Master System, or the MSX computer. You can find flash carts for the SMS to even run your game on the real machine.
